Paid for the order on june 6, june 24 received. The quality is excellent, the sound pleases. Everything is paired with the box in stereo mode. Management works. It came in the usual navel but the box is whole and not a hint of brutality.

Headphones came 2 weeks before thailand. Packaging, of course, damaged, but the main thing is that the headphones are whole. Sound-fire, from the ears do not fall out and for this money generally treasure. Came charged by 10 percent. It is interesting how much is enough full charge, i will add a tip.

I am speechless. This earphones exceeded my expectations! They sound great, there is no audio delay while playing videos (at least on YouTube), they fit into my ears without any problems and both earphones work during calls. I ordered two of them, so my girlfriend and I will enjoy these. I recommend this store and this product. In 60 days, I’ll post another review. By the way, I chose Ali Express Standard Shipping as the shipping method. The products arrived to the country in about 8 days, but the local post (Serpost) delayed the delivery 42 days.
